Playing on a modded multiplayer server I made for friends. Standard start date and time. After watching Life and Living on 7/11 12:00pm, started getting a lot of errors showing in lower right hand corner. Waited for the next L&L episode at 18:00 but the error counter was still counting up. Made a 500mb log file. Most errors show as seen below:
